# Sample toolchain file for building for ARM (w/hw float support) from an Ubuntu Linux system.
#
# Typical usage:
#    1) install cross compiler: `sudo apt-get install gcc-arm-linux-gnueabihf`
#    2) cp cmake/Toolchain-Ubuntu-gnueabihf.cmake.sample ~/Toolchain-Ubuntu-gnueabihf.cmake
#    3) tweak toolchain values as needed
#    4) cd build
#    5) cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-Ubuntu-gnueabihf.cmake ..

# name of the target OS on which the built artifacts will run and the
# toolchain prefix. if target is an embedded system without an OS, set
# CMAKE_SYSTEM_NAME to `Generic`
set(CMAKE_SYSTEM_NAME Linux)
set(TOOLCHAIN_PREFIX /opt/CodeSourcery/armeabi/bin/arm-none-eabi)

# cross compilers to use for C
set(CMAKE_C_COMPILER ${TOOLCHAIN_PREFIX}-gcc)

#   set 1st to dir with the cross compiler's C/C++ headers/libs
#   set 2nd to dir containing personal cross development headers/libs
#set(CMAKE_FIND_ROOT_PATH /usr/${TOOLCHAIN_PREFIX} "${CMAKE_INSTALL_PREFIX}" "${CMAKE_INSTALL_PREFIX}/share" )
